Study the Effect of Fluid Medium toward Synthetic Cancellous Bone Structure

Abstract:

During daily activities, trabecular bone need to bear certain amount of load which also leads to movement of the bone marrow within the structure. The flow of the bone marrow within the trabecular bone structure cause the shear stress which affect the nutrient transport, the properties of the bone and also the bone fatigue life. The aim of this paper is to simulate the trabecular structure using FSI approach in order to study the effect of the fluid flow to the structure. In this study, idealized model with 50% of porosity was used in the simulation and 1mm displacement applied on top of the model. Three different types of analysis were used in order to differentiate between CFD, CSM and FSI results. The results showed significant value between these analyses was concluded that FSI approaches is the best to mimic the real body condition.
